OIL SPRAY OR VAPOR LAMP.

SPECPICATI forming part of Letters Patent No. 382,106, dated May l, 1889. i

Application tiled March 29, 1887. Serial No. 232,882. (No model.) Patented in England June 15, 1886, No. 7,939.

To all whom it may concern.'

Be it known that we, ALEXANDER NErLsoN and JAMES TAYLOR, subjects of the Queen of Great Britain and Ireland, and residents of Inkermann, in the county of Renfrew, Scotland, have invented certain Improvements in Oil Spray or Vapor Lamps, (for which we have -applied for a British Patent, to be dated June 15, 1886, No. 7,939,) of which 'the following 1s a specification.

Our said invention has for its object to improve the construction and action ot lamps of. the kind in which oil is burned for illuminatlng purposes in the form of spray or vapor.

Our improved lamps are designed for being worked with steam; but compressed air may be substituted for the steam, if thought desirable in any case.

In carrying out our invention we employ a vertical burner-body having the oilsupply pipe connected lto the bottom of it. Above the oil-inlet the burner-body is made with an enlargement, to which is connected a pipe sup plying the steam, and at a higher point there is another enlargement by which air is admitted. At the top of the burnerbody there is a slightl y dished or concave flange or disk, and at a Small distance above this disk there is a combustion-chamber, which consists of a metal shell having within it a coil of tubing, and thesteam or compressed air passes through it for the purpose of being superheated; but when dry steam of high pressure is available the special superheating of it may be dispensed with. The oil may be supplied with more or less of a head. The action of the steam or compressed air, if of sufficient pressure, will, however, draw it up from a lower level, if required.

pipe 6 is connected to the burner-body 7 of the lamp close to the bottom of that body,

\ current of steam through the tube.

which is ixed upon a plate, 8, resting by legs 9 upon the top of the tank The oil-inlet into the burnerbody 7 communicates with an internal tube, 10, Fig. 2, formed with a conical nozzle, 11, at its upper end, the position of which nozzle 1l is at an enlargement, 12, formed in the body 7, and having in it the steam-inlet, the steam entering by a lateral pipe, 13. Within the oil-nozzle 1l there is an. adjustable spindle, 14., by preference made, as shown, with a needlepoint passing through the nozzle-Orifice, this spindle passing out through a Stufng-box` and having a handwheel, 15, xed at its bottom end. Above the oil-nozzle 1l there is an internal burnertube, 16, with its bottom end made concave or conical, as shown, and the steam enters between it and the oil-nozzle 11, which is adjustable for regulating the size of the annular passage from the enlargement 12 up between the nozzle and the conical mouth at the bottom of the-inner burner-tube 16. The various parts of the burner-body 7 and the internal tubes, 10 and 16, are connected by a screw-coupling, 17, and other screwed parts, the nozzle-tube 10 being screwed into the lower body part 7, and having the upper body part 7 connected to it by the coupling 17, the adjusting ofwhich determines the position of the nozzle 11 rela* tively to the bottom ot' the inner burner-tube 16. This inner burner-tube 16, the bore of which is of gradually-increasing size from its bottom upward, passes through an upper enlargement, 18, in the upper part of the burner body 7, into which air enters by a side inlet, 19, and from this enlargement the air enters the inner burner-tube1 16 through several apertures, 20, being drawn in by the upward At the top of the burner-body'7 and inner burnertube 16 there is a disk, 2l, and at a small distance above this disk there is a coil of tubing, 22, forming a combustion-chamber, and inclosed in an outer dome-Shaped shell, 28. The steam or compressed air is supplied by apipe, 24, connected to the burner-body b y a blindcoupling and communicating by a pipe, 25, with the coil22, in passing through which the steam or air becomes superheated. 'Ihe other end of the coil connects to the inletpipc 13,

and a stop-cock, 26, and pipe 27 are provided for drawing oiy water due to condensation.v

The shell 23 is made with a top central aperture, 29, for the ignited jet, and is provided with holes to ad mit air which becomes heated between the shell and the superheating-coil 22, and part of the heated air is drawn loeneath the bottom of the coil 22 into the jet of ignited spray, While another part is drawn through a pipe, 28, into the side inlet, 19, of the upper enlargement, 18, in the burnerbody.

Our improved lamp may be used for heating as well as for illuminating purposes.

What We claim as our invention is The combination of the combustion-chamber of a vaporburner with a burnerbody below the chamber, and having upper and lower internal enlargements, a burner-tube within the burner-body opening into the eoinbustion- 2o chamber and extending through and past the said upper enlargement to the lower one and f made with a conical mouth at its lower end,

an adjustable conical nozzle in the lower enlargement for the issue of oil, an inlet for 25 steam or compressed air into the lower enlargement, an inlet for heated air into the upper enlargement, and holes through the burnertube to admit air from the upper enlargement.

In testimony whereof we have signed our 3e names to this specication in the presence of two subscribing witnesses.
